Under pressure to preserve the environment while at the same time ease the poverty of his people, Ecuadorean President Rafael Correa has come up with an unusual solution. Correa wants wealthy nations to pay Ecuador $350 million a year in exchange for leaving an estimated 1 billion barrels of oil under the ground in the pristine Yasuni rainforest.
